Slaves sing most when they are most unhappy. The songs of the slave represent the sorrows of his heart; and he is relieved by them, only as an aching heart is relieved by its tears.

Interpreted as it ought to be interpreted, the Constitution is a glorious liberty document. Read its preamble, consider its purposes. Is slavery among them? Is it at the gateway? or is it in the temple? It is neither.

Let me give you a word of the philosophy of reform. The whole history of the progress of human liberty shows that all concessions yet made to her august claims, have been born of earnest struggle. The conflict has been exciting, agitating, all-absorbing, and for the time being, putting all other tumults to silence. It must do this or it does nothing. If there is no struggle there is no progress.

If there's no struggle, there's no progress.

[John Brown's] zeal in the cause of freedom was infinitely superior to mine. Mine was as the taper light, his was as the burning sun... I could speak for the slave. John Brown could fight for the slave.

Right is of no Sex-Truth is of no Color-God is the Father of us all, and we are all Brethren.

Now, take the Constitution according to its plain reading, and I defy the presentation of a single pro-slavery clause in it. On the other hand it will be found to contain principles and purposes, entirely hostile to the existence of slavery.
